Fuel Filler Flap
RFID Tank Door Sensor
Designated use
The device is used to control the open/closed status of fuel filler flaps in cars. RFID
technology guarantees maximum security, reliability and failure-free operation, unlike
magnetic or inductive devices.
Structure and operation
The device is composed of an RFID reader, a transponder and electronics platform
installed in a metal housing. The reader and transponder are to be mounted in such a way
as to allow them to move towards and away from each other.
When the transponder reaches a given distance, the device compares a 128-bit code
stored in its memory with the transponder's code. Having confirmed that the codes match,
the device will change output status to high. If the transponder is moved out of reader's
range (after opening the fuel filler flap), output status will be changed to low.
Unlike magnetic and capacitive reed relays, the device cannot be tricked with magnets,
coils or other elements. The reader works only with a programmed transponder.
